Some simple and special assistant tools are used in order to improve machining efficiency in the process of high-speed wire cutting .
1)Wire feed tool 1 : As chart9-2 shown, a Φ2mm steel wire is used and bent caudally, a little groove in an inverse V type is cut by wire . This tool is mainly used to make electrode wire gone through the wire hole from top to bottom . Electrode wire is firstly embedded into the little groove in the shape of V type at the bottom ,wire feed tool at right hand, one end of electrode wire was pulled at left hand ,which is gone through the wire hole .
2)Wire feed tool 2 : As chart9-3 shown, a Φ2mm steel wire is used and bent caudally,
a little barb is incised on the lateral of steel wire at the bottom by wire cutting, this tool is mainly used to make electrode wire drawn out from bottom to top and gone through the wire hole . Wire feed tool is firstly inserted into the bottom of wire feed hole when used, then electrode wire hung into the bark, wire feed tool at right hand, one end of electrode wire was drawn at left hand ,pulling up, which makes the electrode wire drawn out from the hole .
3)Wire feed tool : As chart9-4 shown, a Φ2mm steel wire is used and bent caudally, head part is made into semi-circle hook, which is mainly used to make the electrode wire hung in the groove of guide wheel upon wire feeding.
4)Tweezer: As chart9-5 shown, which is mainly used for the wire feed when electrode wire is broken .
5)Flashlight: As chart9-5 shown, which is mainly used to view whether electrode wire is hung on the V type groove of guide wheel and power feed contact, correction of workpieces.
